Do i need to have surgery for a dislocsted disc?

No such thing: Discs don't "dislocate." you may have a bulging disc, and this can be treated a variety of ways such as physical therapy or steroid injections. Surgery is a last resort in most cases.

Herniated: A herniated disc usually does not need surgery, over 90% of the time! but it really depends on the unique situation! and severe symptoms need proper evaluation. Conservative treatment is usually all needed, but there is a trend to mistreat people who need early surgery because of neurological damage. For nerve damage get early evaluation at a high level.
